Re: Parallel solver settings on Windows machine

That is what I also do. I almost never install non-M$ software into the default programs directory, but into something like C:\myprograms. Another example: In ElmerGUI, you may need to move solver xml files from ...\edf-extra to ...\edf. You cannot do that as ordinary user if Elmer is installed in C...

Re: Permanent ring-magnet: axi-symmetric

Hi,

I have never done magnetic simulations myself, but I would not expect the Mgdyn2D solver to work in 3D - you might want to check in the models manual.

Re: ERROR:: StatElecSolve: No > Relative permittivity < found! Error with ELMER GUI tutorial 8

It seems that the material property "relative permittivity" is missing. It is often not contained in the materials in the material library, you need to add it yourself.

Re: Elmergrid doesn't open

Hi, to create a mesh you can * use ElmerGrid format - see tutorials for worked examples * use gmsh, define a geometry, mesh it, save it in msh format (version 2) and convert it with ElmerGrid 14 2 filename.msh - or open it directly with ElmerGUI (File - open) * use Salomé, define a geometry, mesh it...

Re: 2D magnet simulation - unphysical results

Thanks for the pointer. I am using GMSH, tried using coherence command however the mesh doesn't become conformal, any suggestions? Perhaps I need to use a different mesh generator... Hi, you can indeed use Salomé (make a partition before meshing) or use the OpenCascade engine in gmsh which has bool...

Re: Elmergrid doesn't open

Hi, Elmergrid is a commandline application. To use it, open a terminal (enter "cmd" in the start menu if under Windows). Then type e.g. ElmerGrid 14 2 mymesh.msh to convert a gmsh mesh into Elmer format - see Elmergrid Manual for more info. Use File->load mesh in ElmerGUI to open the converted mesh....

Re: 2D magnet simulation - unphysical results

Hi,

have you checked that the mesh is conformal, i.e. the nodes are the same at the interfaces between bodies?

Re: DefaultInitialize: No matrix exists, cannot initialize!

Hi,

Elmersolver doesn't find the mesh.
In your sif file, the third line should read:

Code: Select all

  Mesh DB "." "./Model"

Re: Question by (a total) beginner related to needed pipeline

Hi,

I have read too quickly, sorry. But still you will find starting points in the tutorials, also for elasticity. I would advise to do one or two tutorials and then consult the Models manual where the different solvers are documented.

HTH,
